Abstract
Abstract A method for implementing an operational or functioning test on electrically-actuatable ignition or detonation-triggering circuits for ammunition, wherein the circuits are arranged on board the ammunition. Moreover, also disclosed is an arrangement for the implementation of an operational test of electrically-actuatable ignition or detonation-triggering circuits for the ammunition, wherein the circuits are arranged on board the ammunition.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
104 words
In a method for implementing an operational test on electrically-actuatable ammunition triggering circuits onboard the ammunition, the improvement comprising in firing the ammunition from a stationary launch tube; forming an electrical connection through a tether cable between the ammunition and a stationarily arranged measuring and registering apparatus for test data, the tether cable which is taken along by the ammunition being electrically connected with charging and/or discharging circuits o triggering capacitors; observing and registering the functions of said circuits pursuant to the extent timely time-staggered encounted fluctuations in the potential; and evaluating in the mutual time cycles, the internal functional cycle in the ammunition.
Claim 2
Dependent Claim
104 words
In a method for implementing an operational test on electrically-actuatable ammunition triggering circuits onboard the ammunition, the improvement comprising in firing the ammunition from a stationary launch tube; forming an electrical connection through a tether cable between the ammunition and a stationarily arranged measuring and registering apparatus for test data, the tether cable which is taken along by the ammunition being electrically connected with charging and/or discharging circuits o triggering capacitors; observing and registering the functions of said circuits pursuant to the extent timely time-staggered encounted fluctuations in the potential; and evaluating in the mutual time cycles, the internal functional cycle in the ammunition.
Claim 3
Dependent Claim
38 words
In an arrangement for implementing an operational test on electrically-actuatable ammunition triggering circuits onboard of the ammunition, the improvement comprising in that the triggering circuits are connected through a tether cable with a stationary registering and measuring apparatus.
Claim 4
Dependent Claim
38 words
In an arrangement for implementing an operational test on electrically-actuatable ammunition triggering circuits onboard of the ammunition, the improvement comprising in that the triggering circuits are connected through a tether cable with a stationary registering and measuring apparatus.
Claim 5
Dependent Claim
48 words
An arrangement as claimed in claim 2, wherein said tether cable includes a power supply branch line for the charging of the triggering circuits from a source of current; and means in the registering and measuring apparatus for evaluating the voltage cycle in the power supply branch line.
Claim 6
Dependent Claim
36 words
An arrangement as claimed in claim 2 or 3, wherein said tether cable includes test lines which deliver electrical potentials through uncoupling impedances from trigger elements of the triggering circuits to the registering and measuring apparatus.
Claim 7
Dependent Claim
29 words
An arrangement as claimed in claim 2, wherein the tether cable is deployed as a cable loop extending along about one-half of the expected ballistic trajectory of the ammunition.
Claim 8
Dependent Claim
42 words
An arrangement as claimed in claim 2, wherein a stationary launch tube for the ammunition is equipped with a cable guide for the transient support of the tether cable prior to and during the firing of the ammunition from the launch tube.
Claim 9
Dependent Claim
22 words
An arrangement as claimed in claim 2, wherein the tether cable is conducted by a multi-pole socket plug bar to the ammunition.
Claim 10
Dependent Claim
62 words
An arrangement as claimed in claim 2, wherein, for a stationarily arranged firing launch tube, a supply apparatus for supplying electrical power to the ammunition and for actuation of an ejector is arranged ahead of the firing; and the registering and measuring apparatus and the current source which is connected to the tether cable are arranged in a sideways offset secured shelter.
Claim 11
Dependent Claim
28 words
An arrangement as claimed in claim 2, wherein said tether cable is conducted across a booster amplifier stationarily arranged at one side of the registering and measuring apparatus.
Claim 12
Dependent Claim
17 words
An arrangement as claimed in claim 4, wherein the uncoupling impedances are shunted over by compensating capacitances.
